S = {,,}}
IF S is discrete but infinite,
S = {,,,....} ex. S = {1,2,3,4,...}
S = {sin(2*440t),sin(2*880t),sin(2*1320t),...}
Observe S = is not routable; S = [0,1] is not routable S = {sin(2*f*t)} = {sin(2*f*t)|0}
is all integers -to 
Is routable? yes. ={0,1,-1,2,-2,3,-3, }as opposed to 
= {0,3,e,,-1,1.14,, }
Many different ways to write a set [0,1] = {xsuch that(s. t.) 0x 1} ={real positive numbers no greater than 1 as well as 0}
